PACKAGING DEVICE AND METHOD.

Application filed November 8, 1923. Serial No. 672,681.

To. all whom it may concern.

Be it known that I, OHARLEs R. HULT- GREN, a citizen of theIUnitedStates, re-

siding at Chicago, in the county of Cook and State of Illinois,"haveinvented new and useful Improvements in Packaging Devices and Methods,of which the following is a specification.

This invention relates particularly to an improved device and method forbinding packages, bundles, boxes or the like.

The primary object is to provide'a simple device and an economicalmethod for binding boxes, bundles, etc.

The invention is illustrated in its preferred embodiment in theaccompanying drawing, in which Fig. 1 represents a perspective view of abox or bundle secured by means of the improved packaging device, theview illustrating the manner in which the metal binding tape is drawntaut; Fig. 2, a broken front elevational view of the implement employedin performing. the binding operation; Fig.

2 a broken vertical sectlonal view illustrating the manner in which themetal tape is gripped by the implement during thestretching ortightening operation; Fig. 3,

, a broken perspective view of the improved 1 binding or securingdevice; Fig. 4, a broken perspective view illustrating the condition ofthe binding device while it is being drawn taut; Fig. 5, a similar Viewof the device after the clip hasbeen deformed to secure the bindingtape; and Fig. 6, an enlarged broken sectional view of the bindingdevice in its final condition.

In the illustration given, A represents a package, box or bundle; B, B,the improved binding devicesapplied thereto; and C, an imp'lement whichis adapted to perform the tightening operation and to clipthe metal tapeafter it has been secured.

The improved packaging device is adapt-- ednot only to the purpose ofbinding o-rdi-" nary boxes, crates and packages, but is welladapted tothe purpose of tying-or; securing bundles. For example, the improved de-I I I One useful purpose is that of securing in bundles the arms, legs,rounds, or other members 'of articles of furniture, for example. In thedrawing, A may be regarded may vice may be employed for securmg inbundles, or bales, strips of wood or the like.

as designating any package or bundle which is to be found or baled.

The improved device B comprises a metal band or tape 1 and a clip 2. Thecli'pf2 preferably is formed of sheet metal. It is in the form of a flatplate or disc, preferably punching the intervening metal upwardly.

One end of the .metal band 1 is passed through the slot. 2 from aboveand bent under itself and under the clip, as indicated at 1 The otherend of the band, after encircling the package or bundle is passedthrough the loop 2, so that the extremity 1 652, filed in the Unitedtates Patent Office on the 15th day of October, 1923. Briefly described,it comprises'a foot C, a main lever C and a movable shear member Cconnected-with a rack or plunger O slidablymounted on the lever C saidrack being actuated by a small lever O pivpted on the main lever O I Thefoot C is provided with claws or furcations 3, separated bya space 3.The foot vC is further provided with a tape-channel 4, which is openlaterally to admit the tape, as indicated at 4". The main lever C isfulcrumed on a pivot 5, which extends across. a recess 6 with which themember C. is provided. The lower end of the lever C is received in therecess 6, and therecess 6 communicates with the tape slot 4; or, thebote gripped by the tightening impletom of the slot 4 maybe regardedas-the 7 bottom of the recess 6. The lower'end of the lever O has anextension 7 which serves to grip the tape against the bottom of thetape-channel 4 when stretching force is ex; erted on the lever C Themember C a is provided with a shear member 8 which co-operates with themovable shear O". The shear member C is capable of limited verticalmovement with respect to the member C. The shear member C is providedwith slots 9 through which extends screws 10 which serve, to secure theshear member to'the foot. v

In the useof the improved device, a suit able length of metal tape issevered from a roll; one end of the tape is secured to the clip in themanner illustrated in Fig. 3; the tape is then passed about the packageor bundle and the free end inserted through the loop 2", as indicated inFig.4, the free end portion of the tape is A then passed through thestretching implement, which is positioned preferably as shown in Fig. 1,the points of the furcartions 3 bearing against the edge of the clip..As the lever (l is actuated, it causes thetape to be gripped "by the'gripping member 7 against the bottom wall of the tapechannel, and thewhole implement then acts as a lever to tighten the tape. After the tapehas been drawn sufficieiitly taut, the loop 2 is struck with a hammer,thus forcing the loop into the plane or substantially into the plane ofthe body a of the clip and at the same time deforming the tape andbinding it in the slots 2*and 2 and about the loop or bridge piece 2.The small lever C may then be operated to clip ofi' such portion of thetape as'extends be "yond the shear member. The slots 2 and 2 arepreferably very narrow sothat when the bridge piece is hammered down soas to he very close to the plane of the body of the 0 clip, the tapeWill be securely gripped between the edges of the bridge piece and thewalls of the slots. JXS an additional security, the free end 1 of thetape may be folded back upon the tape as indicated in Fig. 6.

' By means of the improved packaging device and method, packagingoperations of the character indicated inay be performed very rapidly andwith great security.

\Vhat I regard as new, and desire to secure by Letters Patent, is:

l. A packaging device. comprising a clip and a metal tape having one endsecured to said clip, said clip being formed with a loop adapted topermit the free end of the through said loop, said loop being depressed'andthe tape being deformed and gripped 'within said slots by the loop.

73 Aq'i'ackaging device comprising a sheet metal clip provided'witliapair of slots and an intervening bridge piece, and a. metal tape havingone extremity passing through one of said slots i'romabove and bentback-' vsardly under the clip and having the other extremity extendingunder the bridge piece and gripped thereby within said slots, said lastnamed extremity being bent upon itself over the clip.

4. The method of packaging which compriscs applying to the package adevice cort pi'isii'ig a metal clip provided with a loop and a metaltape having one end secured to said clip and the other extremityextending through said loop, drawing the tape taut through said loop,and deforming the loop to grip the tape.
